Ethereal segfaults while sniffing in non/promiscuous mode on SuSE 10.1 fully
patched. I have rebooted and reinstalled ethereal.

Compiled with GTK+ 2.8.10, with GLib 2.8.5, with libpcap 0.9.4, with libz
1.2.3,
with libpcre 6.4, with Net-SNMP 5.3.0.1, with ADNS.

Running with libpcap version 0.9.4 on Linux 2.6.16.21-0.13-smp.

uname -a 
Linux linux-server 2.6.16.21-0.13-smp #1 SMP Mon Jul 17 17:22:44 UTC 2006 i686
i686 i386 GNU/Linux

==Steps to reproduce==
1) Launch ethereal as root on SuSE 10.1.
2) Sniff the network (promiscuous mode it doesnt matter)
3) Use the net command to attemt to join samba to a active directory domain.
"net ads join" and a mis typing "net join ads".
4) Notice how ethereal quits "Segmentation fault".

I'm not sure what else to attach as this is my first bug crash report on linux.
